Evolutionary context of genes as related to CGS scores. The proteins encoded by the chromosome (A) or five plasmids (B) of Synechocystis PCC 6803 were ordered by their CGS scores and divided into four categories: cyanobacterial, non-cyanobacterial, recent origin, and solitary, as described in the text and Methods. Each point on the graph is a frequency based on 50 proteins centered around the CGS ranking. The blue shaded areas indicate genes with CGS scores < 0.05.
